What is electron configuration?

Back

The distribution of electrons in an atom's orbitals, indicating the energy levels and sublevels occupied by electrons.

Front

What does the notation 1s² 2s² 2p⁶ represent?

Back

It represents the electron configuration of an atom, showing the number of electrons in each subshell.

Front

How many electrons can the s sublevel hold?

Back

2 electrons.

Front

How many electrons can the p sublevel hold?

Back

6 electrons.

Front

What is the maximum number of electrons in the third energy level?

Back

18 electrons (2 in s, 6 in p, and 10 in d).

Front

What is the Diagonal Rule in electron configuration?

Back

A guideline for determining the order in which orbitals are filled based on increasing energy levels.

Front

Which block of the periodic table contains the elements with the highest energy electrons in p orbitals?

Back

The p-block.

Front

What is the significance of the principal quantum number?

Back

It indicates the main energy level of an electron in an atom.

Front

What is the difference between core electrons and valence electrons?

Back

Core electrons are those in filled inner shells, while valence electrons are in the outermost shell and involved in bonding.
